Title: Image forming device
Inventor: MATSUZOE HISANOBU
IPC: G03G21/00
Filed: 1990-02-02
Abstract: PURPOSE:To decrease the number of parts and reduce the cost, and to reduce the size of the device by providing a rotary body which transfers toner on a toner sticking member to a recording medium which is conveyed by a conveying means, and collects residual toner on the toner sticking member after transfer after the recording medium passes. CONSTITUTION:When a composite image is formed on an intermediate transfer belt 8, a voltage is applied to the transfer cleaning roller 15 of a transfer cleaner 14, the transfer cleaning roller 15 which is applied with the voltage moves to energize transfer paper 11 against the intermediate transfer belt 8 by a separating and contacting means, and the composite image is transferred to copying paper 11. Even after the transfer, the transfer cleaning roller 15 does not move to its original position, the rotating speed is switched to a speed faster than that in the transfer, and residual toner is scraped by the friction between the transfer cleaning roller 15 and intermediate transfer belt 18. Consequently, one rotary body serves as both a transfer device and a cleaner for collecting the residual toner, so only one separating and contacting means is required to reduce the cost and size of the device by decreasing the number of parts.
